Vulnerability and Resilience Research:A Critical Perspective

International Journal of Disaster Risk Science 2014年第1期5卷 86-87页

‘‘Vulnerability’’and‘‘resilience’’are terms of such broad conceptual meaning as to be almost useless for careful scientific communication,except as rhetorical indicators of areas of greatest *** is a reflection of the complexity of their meaning,an uncoordinated search among different fields for a common understanding,and maybe the difficulty of systematizing these complicated issues among the various involved parties.

Urbanization between compactness and dispersion:designing a spatial model for measuring 2D binary settlement landscape configurations

Measuring spatial patterns is a crucial task in spatial *** indicators have been developed to measure patterns in a quantitative ***,most comparative studies rely on relative comparisons,limiting their explanatory power to specific case *** by advancements in earth observation providing unprecedented resolutions of settlement patterns,this paper suggests a measurement technique for spatial patterns to overcome the limits of relative *** design a model spanning a feature space based on two metrics-largest patch index and number of *** feature space is defined as‘dispersion index’and covers the entire spectrum of possible two-dimensional binary(settlement)*** model configuration allows for an unambiguous ranking of each possible pattern with respect to spatial *** spatial resolutions of input data as well as selected areas of interest influence measurement results,we test dependencies within the ***,common other spatial metrics are selected for testing whether they allow unambiguous *** scenarios,we apply the model to artificially generated patterns representing all possible configurations as well as to real-world settlement classifications differing in growth dynamics and patterns.
